0A and 10B supply the conveyors 11A and 11B.

The lifters 12A, 12B descend after receiving an empty pallet from the pallet magazine 21.

When the in-vehicle pallets are placed on the conveyors 11A and 11B, the stacker crane 1 stops so that the forks 2A are positioned on the fourth rows of the shelf groups 4 and 5. Then, the forks 2A are simultaneously projected to the conveyor 11B and the forks 2B are simultaneously projected to the conveyor 11A, and the in-vehicle pallets are simultaneously taken into the stacker crane 1 side. Next, the stacker crane 1 stores the in-vehicle pallet in the empty shelf.

As described above, the stacker crane 1 simultaneously transports two in-vehicle pallets when warehousing is continuous, and in other cases, the pallets are transported one by one.

Next, the unloading operation (pattern (2)) will be described for the shelf groups 4 and 5. The driver who requests the leaving of the car inserts the parking card into the terminal installed at the entrance 56 and instructs the leaving of the car. Since the position (number) of the entrance / exit opening from which the vehicle exits is indicated from the terminal device, the passage 5

The stacker crane 1 takes out the in-vehicle pallets from the two shelves to which the delivery command has been issued, and stops so that the forks 2A are located on the fourth rows of the shelf groups 4 and 5. Then, the forks 2A are simultaneously projected to the conveyor 10A, and the forks 2B are simultaneously projected to the conveyor 10B, and the conveyors 10A, 10B on the upper surfaces of the lifters 12A, 12B that are rising and waiting.
Then, two pallets are mounted on the car at the same time.

Next, when the lifters 12A and 12B are lowered, the exit door 41 is opened, and the driver gets on the vehicle and exits. Then, the passenger once stops and gets on the passenger who has passed through the passage 55, and reaches the exit 31 through the exit path 36.

When the vehicle leaves, the exit door 41 is closed, the lifters 12A and 12B are raised, and the empty pallets 39 are stacked on the pallet magazine 21.

As described above, the stacker crane 1 simultaneously transports two in-vehicle pallets when the delivery is continuous, and in other cases, the pallets are transported one by one.

Next, the case where the unloading operation and the warehousing operation are alternately repeated (pattern (3)) will be described with respect to the shelf groups 4 and 5.

In a general parking lot, vehicles waiting for entry are waiting in front of the entrance / exit opening, and when a parked vehicle exits and an empty shelf comes out, the majority of cases enter immediately. That is, when there is a vehicle waiting for entry before the entrance / exit ports 13A and 13B, the exit door 41 is opened and the vehicle exits, and then the exit door 41 is closed and the entrance door 40 is opened at the same time. An empty pallet 39 remains on the upper surfaces of the lifters 12A and 12B.
Enter 3A, 13B. After the driver gets off the vehicle, the entrance door 40 is closed according to a parking instruction, and the lifters 12A and 12A are closed.
B rises and the pallets mounted on the vehicle move on conveyors 11A and 11B.
Supplied to The lifters 12A and 12B stand by in a state of being raised.

During the above-mentioned loading operation, the stacker crane 1 takes out the two in-vehicle pallets for which the loading instruction has been issued, and moves the fork 2A so that it is positioned on the fourth row of the shelf groups 4 and 5. Stop. If the in-vehicle pallets to be stored are moved to the conveyors 11A and 11B, the fork 2A is moved to the conveyor 10A, and the fork 2B is moved to the conveyor 10A.
B on the conveyor 10
A and 10B at the same time.

Next, the stacker crane 1
A, 2B are simultaneously withdrawn from conveyors 10A, 10B,
Conveyors 11B and 11A without stopping midway
At the same time, and take in two pallets at the same time. Next, the stacker crane 1 stores the in-vehicle pallet in the empty shelf.

On the other hand, when the conveyors 10A and 10B receive the in-vehicle pallets to be unloaded from the stacker crane 1, the lifters 12A and 12B are lowered, the exit door 41 is opened, and the driver gets on the vehicle and leaves.

Thereafter, this is repeated. As described above, the stacker crane 1 simultaneously transports two in-vehicle pallets when storage and retrieval are continuous.

A case will be described in which one of the outgoing or incoming is one. Shelf groups 4 and 5 will be described for a case where there is one warehouse and two warehouses.

The two vehicles to be stored are simultaneously supplied to the conveyors 11A and 11B according to the procedure described above. The stacker crane 1 takes out the in-vehicle pallet from the shelf by the fork 2A in response to the delivery command, and the fork 2A
Stop so as to be located on the fourth line of No. 5. Next, the vehicle-mounted pallet is placed on the conveyor 10A by the fork 2A, the fork 2A is retracted, and then the fork 2A is moved to the conveyor 1A.
1B. At this time, in synchronization with the fork 2A, the fork 2B is protruded from the conveyor 11A, and two in-vehicle pallets are taken in at the same time. After that, stacker crane 1
Stores two onboard pallets on empty shelves.

On the other hand, when the conveyor 10A receives the in-vehicle pallet from the stacker crane 1, the lifter 12A descends, the exit door 41 opens, and the driver gets on the vehicle and leaves.
An empty pallet is supplied to the conveyor 10B from the pallet magazine 21, and the lifter 12B is lowered.

When the shelves instructed to be taken out are on the fifth to eighth rows of the shelves 4 and 5, the stacker crane 1 takes out the in-vehicle pallet from the shelves by using the forks 2B.
Stops on the fifth row of the shelf groups 4 and 5. In this case, the on-board pallet is transported by the fork 2B to the conveyor 10.
Put on B and leave. An empty pallet is supplied from the pallet magazine 21 to the conveyor 10A.

Next, the case where the number of warehouses is two and the number of warehouses is one is as follows.
The shelf groups 4 and 5 will be described. For example, a description will be given of a case in which there are two exit commands, but there is no entry waiting vehicle at the entry / exit opening 13B but only in front of the entry / exit opening 13A.

The entering vehicle enters the entrance 13A according to the procedure described above, the lifter 12A rises, and the pallet is supplied to the conveyor 11A. At the same time, the lifter 12B rises with the empty pallet placed thereon, and the empty pallet is moved by the conveyor 10B to the pallet magazine 21B.
To be stacked. The stacker crane 1 receives two in-vehicle pallets from a shelf, and places the in-vehicle pallets on the conveyors 10A and 10B with forks 2A and 2B, respectively. Next, the fork 2B is retracted from the conveyor 10B, and subsequently protruded from the conveyor 11A to receive the in-vehicle pallet. At this time, the fork 2A is retracted from the conveyor 10A in synchronization with the fork 2B, but does not protrude from the conveyor 11B. Stacker crane empties one vehicle pallet
Store on shelves .

The above operation is performed by a computer.
The computer determines the status of the retrieval request, the entrance / exit port 13A, 1
The operation procedure is determined by detecting the presence / absence of a pallet at 3B and each transfer port, the number of vehicles waiting to be stored, and the like.

It should be noted that there are other ways of entering and leaving the warehouse. For example, when a plurality of vehicles are going to enter the one entrance / exit opening 13A side and there is no vehicle on the other entrance / exit opening 13B side, the stacker crane 1 moves the two vehicle-mounted pallets of the conveyors 11A and 10A. They will be transported at the same time.

The entry / exit port 13A can be used for entry and the entry / exit port 13B can be used exclusively for exit. In this case, two in-vehicle pallets can be unloaded to the conveyors 10B and 11B at the same time, and two in-vehicle pallets can be taken into the stacker crane 1 from the conveyors 10A and 11A at the same time. Since the entrance / exit port 13A located on the upstream side in the traveling direction of the vehicle is used for entry and the entrance / exit port 13B on the downstream side is used for exit, the operation of the vehicle can be facilitated.

As described above, the shelves 4 and 5 are provided with the loading / unloading ports 13A and 13B, respectively, and one fork 2A is connected to the transfer port of one shelf group and the other fork 2B is transferred to the transfer port of the other shelf group. Protrude simultaneously and stack two vehicles at the same time
From lane 1 to the transfer port (or from the transfer port to the stacker
When transporting each unit.
In comparison, the time required for loading and unloading per vehicle can be reduced. For example, this effect can be easily understood if only two cars are taken out or two cars are taken in.

Each of the shelf groups 4 and 5 has a transfer port 10E, 11
E, 10F, and 11F are provided two by two, and the position (height and interval) of the transfer port is determined by the fork 2A of the stacker crane 1,
It is provided in accordance with the position (height, interval) of 2B. That is,
The transfer ports 10E and 11E of one shelf group and the transfer port 11 of the other shelf group
F and 10F face each other across the forks 2A and 2B. The faces may transfer opening 10E for unloading, 10F and transfer opening 11 F, 11 E for receipts. For this reason, while the stacker crane is stopped, the two in-vehicle pallets are simultaneously transferred to the delivery ports 10E and 10F for delivery, and at the same stop position, the opposite delivery ports 11F and 11F for entrance.
You can receive two onboard pallets from E at the same time,
Entry and exit can be performed in a very short time.

Further, between the pallet magazine 21 and the receiving / receiving ports 11E, 11F , the receiving / receiving ports 10E, 10F are provided.
Since F is provided , the transport distance of the empty pallet can be minimized. In particular, when entry and exit are alternately repeated, empty pallets need not be transported at all, and entry and exit can be performed more efficiently in a short time. Further, with the above arrangement, it is not necessary to provide a transport path dedicated to empty pallets at the lower part of the shelf, and the height of the shelf can be reduced. This can be understood by assuming, for example, a case where the pallet magazine 21 of the shelf group 4 is set on the sixth row.

The transfer port 10 with the stacker crane 10
Since E, 10F, 11E, and 11F are provided substantially at the center in the longitudinal direction of the shelf group, the traveling distance of the stacker crane can be minimized, and the distance from the entrance to the entrance of the parking lot can be reduced. It can take enough distance,
The vehicle can easily enter and exit the entrance and exit.

As described above, by providing a set of entrance / exit, a lifter, a pallet magazine, and a conveyor for one set of shelves, the shelves with a small number of rows and a large number of shelves can be extremely efficiently used. It is possible to enter, park and leave.

Further, when a group of shelves is arranged side by side, the entrance and exit ports, lifters and the like are arranged at least one line apart, so that the space for the platform for occupants to get on and off is reduced below other shelves. It can be positioned and has the effect that no special space is required between the opposing shelves.

[0064] Further, enters <br/> path 35 of the vehicle occupant of the passage 50 and 55, since arranged above the exit road 36, prevents the occupant across the entrance road 35, exit passage 36 of the vehicle,
You can do it safely. In particular, this is effective in a large parking lot in which a number of entrances and exits are arranged side by side. In addition, since the stairs connecting the entrance / exit surface and the passages 50 and 55 are provided below the traveling path 3 of the stacker crane 1, the space can be effectively used and the multi-story parking lot can be enlarged in the width direction. It can be prevented.

In the embodiment shown in FIG. 5, in the shelf groups 4 and 5, the entrance / exit port and the exit / exit port are exchanged. The stacker crane 1 uses a fork 2A, 2B to convey a vehicle-mounted pallet to be delivered to a conveyor 11B,
11A, the pallets to be loaded and stored on the conveyor 10
A, received from 10B.

According to this embodiment, the conveyor 10 is provided on the upper surface.
Even if the lifters 12A, 12B carrying the A, 10B are not raised, the out-of-stock pallets can be delivered to the delivery port, and if the lifters 12A, 12B are further raised,
Since the in-vehicle pallets that are immediately stored can be received, the waiting time of the stacker crane 1 can be reduced.

The embodiment shown in FIGS. 6 and 7 will be described. In the group of shelves 4, the pallet magazine 21, the conveyor 10A of the entrance / exit 13A, and the conveyors 45A and 46A are provided in series. In shelf group 5, pallet magazine 2
1, Conveyor 10B, Conveyor 45 of loading / unloading port 13B
B and 46B are provided in series. These devices are installed in the same row in the shelf group 4 and the shelf group 5.

When the loading and unloading are performed alternately, the stacker crane 1 unloads the conveyors 45A and 46B at the same time , and then receives the in-vehicle pallets from the conveyors 46A and 46B at the same position.

Further, after the goods are unloaded to the conveyors 10A and 45B at the same time, and after traveling one line, the conveyors 45A and 46B
It is also possible to receive the in-vehicle pallet from B at the same time.

Conversely, the articles are simultaneously unloaded to the conveyors 45A and 46B, and after traveling one line, the conveyors 10A and 45B
B can receive the in-vehicle pallet at the same time.

The conveyors 45A, 46A (45B,
46B) or the conveyors 10A, 45A (10B, 45
B) can be exchanged as a set. Conveyor 46
A and 46B are buffers.

Efficiency can be improved by switching these appropriately according to the situation. In this embodiment, the entrance 13
A and the entrance / exit 13B can be installed on the same line, so that, for example, the straight portion of the approach path 35 in front of the entrance / exit can be lengthened,
It is easy to enter the entrance.

Also, since the entrance / exit port 13B of the shelf group 5 and the entrance / exit port 13A of the adjacent set of shelves 4A are installed in the same row, the space between the adjacent sets, that is, A space for the platform 43 is provided between the rack group 4 and the shelf group 4.

In FIG. 7, the passage 50 is also used for getting on and off. Numeral 60 is a passage for retrieval. Also, a stair can be added to the space S. In each of the above embodiments,
Although the stacker crane 1 has two forks, the same applies to a stacker crane having one fork.

In each of the above embodiments, the shelf storage area is provided above the entry / exit area, but may be provided below. FIG. 8 shows an example. Lifter 12A
Are supported by the shelf group 4. Reference numeral 49 denotes a floor for the approach path 35 and the like.

[0076]

According to the present invention, since the transfer port and the pallet magazine are provided centering on the lifter, the transport distance of the empty pallet and the in-vehicle pallet can be shortened, and the time for loading and unloading can be shortened.
